Clean Energy

Google has announced that its innovative advanced geothermal plant in Nevada is now operational and connected to the grid, pioneering an approach that promises to unlock clean, always-on geothermal energy across a much larger range of locations.

In an average day, tropical oceans absorb about 278 petawatt-hours of solar energy. Harvesting just 1/4000th of that energy would supply the entire world's daily electricity – and ocean thermal energy conversion provides a possible method.

It looks nothing like a typical "fan on a stick" wind turbine, but this oval track with evenly spaced wing blades could be an enormously disruptive addition to the renewable energy mix, since it slashes the cost of wind power to unprecedented lows.

A wildly innovative turbine that could halve the cost of offshore wind is set to go into testing in Norway. The 19-m (62-ft), 30-kW, contra-rotating vertical-axis turbine is a prototype of a design that could scale to unprecedented size and power.

Imagine something as tall as New York's Chrysler building, but spinning. China's Mingyang Smart Energy has announced plans for a colossal 22-megawatt offshore wind turbine, and standing in its presence will be an unprecedented human experience.

Three Gorges Energy has connected the world's first 16-megawatt monster offshore wind turbine to the power grid. With a mind-boggling 260-meter (853-ft) rotor diameter, this towering colossus will supply clean energy for about 36,000 Chinese homes.

Fervo's "next-generation geothermal" technology has proven itself in testing, becoming the most productive enhanced geothermal plant in history. The company hopes its approach will radically expand access to clean energy, like shale did for oil.

Slovakia's GA Drilling has demonstrated a pair of new technologies it says could unlock geothermal power generation more or less anywhere on the planet. Anchorbit and Plasmabit promise much faster and cheaper drilling into hot rock 10 km underground.

Japanese company PowerX is moving ahead with its strange plan to build a "mobile power station" in the form of a 140-meter (460-ft) electric "battery tanker," which will carry 241 megawatt-hours of renewable energy across the sea over short distances.

In an outrageously audacious move, Washington-based fusion power startup Helion has signed the world's first fusion power supply deal, promising to deliver Microsoft at least 50 megawatts of clean fusion power by 2028, or pay financial penalties.

Irish company Gazelle has announced the third generation of a fascinating new floating wind platform design it says can stabiliize massive offshore turbines up to 20 MW in capacity, while radically reducing weight, cost and sea floor cable tension.

Studying how bacteria interacts with the environment, a microbiology team discovered a powerhouse of an enzyme that consumes hydrogen and turns it into electricity. Researcher Rhys Grinter told New Atlas what the findings could mean for clean energy.
